Win 7 Ultimate is a combination of Win 7 home edition and the professional edition. It include all of the media stuff.

OK. I dragged the desktop down to the shop and loaded the tuning software. It works.

A thought that I had is that the tuning software isn't compatible with Win 7 64 bit. Both computers that run the software successfully are running 32 bit operating systems; one on XP and the other Win 7.

AM SOOO glad U said this, cos was contemplating a new 64 bit system after finding out the hard way that its impossible to program the piccolo using ver 8, 32 bit of the IDE.
Clough's f/w was written in the 64 bit environs. I used another pc to do the programming & will use this 17" laptop for the tuning.

we seem to have missed the elephant in the room! or i did anyway
Re Briney eye & Leadscrew loading, 700 lb+ carriage forces etc, you obviously succeeded with the 25th D.O.C.'s for the 8 TPI or whatever,
So does this mean a loading capability of 700lb+ not required or?

Thinking about it, the laptop is running Win 7 32 bit as welll so I am at a loss as to why I can't connect with the laptop.

Laptops are an issue for lots of reasons, will be a hardware compromise somewhere.
As an example, My longstanding friend, just tonight, reminded me not to use a laptop for fast applications.

It doesn't take a lot of force on the carriage crank to stall out the stepper. I calculated that I have a mechanical advantage of 11:1 with my hand crank so a few simple measurements should indicate the maximum force that the stepper can deliver to the carriage. Back in post #132, I made some measurements of stall force that were fairly anemic but since then, I changed the gear ratio and increased the driver voltage. I did some rough measurements this morning and it would be safe to say that I don't have much more than 100 lbs of force available.

I really need some way of applying a direct force to the carriage. Possibly a line over a pulley at the tailstock end lifting a dead weight?I have a pulley mounted for the flexible conduit from my cross slide DRO already.

I like the simple pulley/ weight approach. But, if u have only 100lb or so at your disposal, then how come it cuts as quoted?
Surely it should have failed to cut.. anyway, regardless of computations, & anticipated requirements, it worked on your particular machine!
U must feel the need for more grunt!
BTW, in the process of updating a laptop to win10, from 7. On a 64 bit machine.
All done via MS, & a downloaded .iso file from them. All free. Just hope nothing goes wrong.

The truth will come out when I do the test. Based on the force required to turn the carriage crank in the past, 100 lbs. is probably sufficient. I will see.
I am a bit disturbed by the fact that I can stall out the stepper with so little force and would like it to be higher. I prefer to have more of an operating margin. OTOH, I could just consider it to be a safety feature by stalling out and preventing a serious crash.

yes i like the safety idea,, TBH, i crashed my machine when learning threading
